Description

Technical Field

[0001] This invention discloses a protective fixation device for pediatric radiological examinations. Background Technology

[0002] Currently, when radiology departments conduct physical examinations on children, some younger children are quite playful and hyperactive, often requiring the use of protective restraint devices. While existing protective restraint devices can achieve the basic function of securing children, their fixed design means that they cannot properly restrain taller or shorter children due to significant differences in height, thus reducing their applicability.

[0003] Meanwhile, existing protective restraint devices are cumbersome to use when securing children, and some children resist when being restrained, resulting in children breaking free before the restraint is completed. This increases the difficulty of the operation for medical staff and reduces the efficiency of examining children.

[0004] Furthermore, existing protective restraint devices often fail to fit snugly against a child's arm, leaving gaps between the child's arm and the device. This can cause children to swing and pull their arms from side to side in an attempt to break free, potentially resulting in scratches on their skin. Summary of the Invention

[0005] The purpose of this invention is to provide a protective restraint device for pediatric radiological examinations, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a protective fixing device for pediatric radiological examinations, comprising a detection device and a movable detection plate, wherein a fixing rod is fixedly installed inside the movable detection plate, a limiting rod is movably sleeved on the outer surface of the fixing rod, rotating rods are movably sleeved on both sides of the movable detection plate, a movable frame, a first movable block and a second movable block are movably sleeved on the outer surface of the limiting rod, a limiting plate is hinged to the top of the movable frame, a first long rod is movably sleeved inside the first movable block, a movable plate is fixedly connected to the top of the first long rod, and a second long rod is fixedly connected to the right side of the movable plate.

[0007] Preferably, a circular shaft is fixedly installed inside the limiting plate. A first rectangular block, a flexible spring, and a second rectangular block are movably sleeved on the outer surface of the circular shaft from top to bottom. A limiting shaft is fixedly sleeved on the bottom of the second rectangular block. A fixing tooth is fixedly installed on the front of the limiting plate. An installation plate is fixedly installed on the front of the first rectangular block. A circular rod is fixedly installed inside the installation plate. A rigid spring and a movable tooth are movably sleeved on the outer surface of the circular rod from left to right. A clamping block is fixedly installed on the back of the first rectangular block. Due to the design of the circular shaft, the first rectangular block can move up and down along the inside of the circular shaft through the cooperation between the first rectangular block and the circular shaft, thereby driving the first movable block to fit against the child's arm.

[0008] Preferably, there are two limiting rods, and the cross-section of the two limiting rods is semi-circular. The limiting rods are threadedly connected to the rotating rod. Due to the design of the limiting rods, the cooperation between the limiting rods and the rotating rods allows the rotating rods to drive the limiting rods to move left and right along the outer surface of the fixed rods. This allows the limiting rods to press against the inner walls of the movable frame, the first movable block, and the second movable block, thereby increasing the friction between them and limiting the movement of the limiting rods.

[0009] Preferably, the outer surface of the rotating rod is provided with two sections of thread, the two sections of thread are in opposite directions and are located on both sides of the limiting rod. Due to the design of the rotating rod, the two sections of thread are opposite, so that when the rotating rod rotates, the two limiting rods can be driven to move towards or away from each other through the cooperation of the rotating rod and the limiting rod.

[0010] Preferably, the movable plate is arc-shaped, and the right end of the second long rod is movably connected to the second movable block. Due to the cooperation between the first movable block and the first long rod, the first long rod can drive the movable plate to rotate along the inside of the first movable block. At this time, through the cooperation between the second movable block and the second long rod, the second movable block can move left and right along the outer surface of the limiting rod and be sleeved on the outside of the second long rod. At the same time, the rotation of the rotating rod can drive the limiting rod to limit the first movable block and the second movable block respectively, thereby fixing the child's legs.

[0011] Preferably, the two ends of the flexible spring are fixedly connected to the first rectangular block and the second rectangular block respectively, and the limiting shaft is movably sleeved with the movable frame. Due to the design of the flexible spring, when the first rectangular block is in a fixed state, the second rectangular block has good elastic reset performance. At this time, the flexible spring is in a compressed state, so it will apply an elastic force to the second rectangular block, thereby driving the limiting shaft into the interior of the movable frame to limit the limiting plate.

[0012] Preferably, the right side of the movable locking tooth is a right-angled triangle. The movable locking tooth meshes with the fixed locking tooth. Due to the design of the movable locking tooth, the movable locking tooth can move up and down through the cooperation between the first rectangular block and the round shaft via the mounting plate. When the inclined surface of the movable locking tooth presses against the fixed locking tooth, the movable locking tooth will move to the left along the outer surface of the round rod and separate from the fixed locking tooth. This allows medical personnel to push the mounting plate downward. At the same time, since the flexible spring is in a compressed state, a thrust can be applied to the movable locking tooth, so that when the movable locking tooth separates from the fixed locking tooth, it can drive the first rectangular block to reset, thereby driving the clamping block to separate from the child's arm.

[0013] Preferably, the two ends of the rigid spring are fixedly connected to the movable locking teeth and the mounting plate, respectively. The inner side of the clamping block is glued with silicone. Since the rigid spring is in a compressed state, it will apply an elastic force to the movable locking teeth, thereby making the fit between the movable locking teeth and the fixed locking teeth tighter. At the same time, since silicone has good elasticity and softness, it makes the child's arm more comfortable.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention, by setting a limiting rod, a rotating rod, a movable plate, and a second movable block, allows the movable frame, the first movable block, the second movable block, and the limiting rod to move left and right along the outer surface of the limiting rod. This allows the position of the movable frame to be adjusted according to the position of the child's arms, and the position of the first movable block to be adjusted according to the position of the child's legs. By rotating the left rotating rod, the two threads on its outer surface can drive the limiting rod to move in opposite directions, thereby positioning the first movable block. Simultaneously, the cooperation between the first long rod and the first movable block can drive the movable plate to rotate. Furthermore, the cooperation between the second movable block and the limiting rod can cause the second movable block to engage with the second long rod. By rotating the right rotating rod, the second movable block and the movable frame can be positioned. Therefore, the fixed position can be adjusted according to the child's height.

[0016] 2. This invention, by setting up a movable frame, a limiting plate, a flexible spring, and a limiting shaft, allows the second rectangular block to move up and down along the outer surface of the flexible spring through the cooperation between the second rectangular block and the round shaft. At the same time, due to the cooperation between the movable frame and the limiting plate, the limiting plate can rotate along the top of the movable frame. At this time, since the flexible spring is in a compressed state, it will apply an elastic force to the second rectangular block. Thus, the limiting plate is limited by the cooperation between the limiting shaft and the movable frame to prevent the limiting plate from rotating, thereby quickly limiting the child's arm.

[0017] 3. This invention, by setting up fixed teeth, a rigid spring, movable teeth, and a clamping block, allows the first rectangular block to move up and down along the outer surface of the round shaft due to the cooperation between the first rectangular block and the round shaft. This allows the movable teeth to press against the fixed teeth via the mounting plate. When the inclined surface of the movable teeth presses against the fixed teeth, the movable teeth will move to the left along the outer surface of the round shaft and separate from the fixed teeth, thus releasing the mounting plate from its limit. This allows the clamping block to fit more tightly against the child's arm via the first rectangular block. At this time, since the rigid spring is in a compressed state, it will apply an elastic force to the movable teeth, thereby positioning the clamping block through the cooperation between the movable teeth and the fixed teeth, thus preventing the child's arm from moving.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown in the embodiment of the present invention, a protective fixing device for pediatric radiological examinations includes a detection device 1 and a movable detection plate 2. A fixing rod 3 is fixedly installed inside the movable detection plate 2. A limiting rod 4 is movably sleeved on the outer surface of the fixing rod 3. Rotating rods 5 are movably sleeved on both sides of the movable detection plate 2. A movable frame 6, a first movable block 19, and a second movable block 20 are movably sleeved on the outer surface of the limiting rod 4. A limiting plate 7 is hinged to the top of the movable frame 6. A first long rod 21 is movably sleeved inside the first movable block 19. A movable plate 22 is fixedly connected to the top of the first long rod 21. A second long rod 23 is fixedly connected to the right side of the movable plate 22.

[0028] The limiting plate 7 has a circular shaft 8 fixedly installed inside. The outer surface of the circular shaft 8 is movably sleeved with a first rectangular block 9, a flexible spring 10, and a second rectangular block 11 from top to bottom. The bottom of the second rectangular block 11 is fixedly sleeved with a limiting shaft 12. The front of the limiting plate 7 is fixedly installed with a fixing tooth 13. The front of the first rectangular block 9 is fixedly installed with a mounting plate 14. The inside of the mounting plate 14 is fixedly installed with a circular rod 15. The outer surface of the circular rod 15 is movably sleeved with a rigid spring 16 and a movable tooth 17 from left to right. The back of the first rectangular block 9 is fixedly installed with a clamping block 18. Due to the design of the circular shaft 8, the first rectangular block 9 can move up and down along the inside of the circular shaft 8 through the cooperation between the first rectangular block 9 and the circular shaft 8, thereby driving the first movable block 19 to fit against the child's arm.

[0029] In this embodiment, there are two limiting rods 4, and the cross-section of the two limiting rods 4 is semi-circular. The limiting rods 4 are threadedly connected to the rotating rod 5. Due to the design of the limiting rods 4, the cooperation between the limiting rods 4 and the rotating rod 5 allows the rotating rod 5 to drive the limiting rods 4 to move left and right along the outer surface of the fixed rod 3. This allows the limiting rods 4 to press against the inner walls of the movable frame 6, the first movable block 19, and the second movable block 20, thereby increasing the friction between them and limiting rods 4 to limit their movement.

[0030] The outer surface of the rotating rod 5 is provided with two sections of thread, which are opposite in direction and located on both sides of the limiting rod 4. Due to the design of the rotating rod 5, the two opposite threads allow the two limiting rods 4 to move towards or away from each other when the rotating rod 5 rotates. Specifically, the movable plate 22 can be arc-shaped, and the right end of the second long rod 23 is movably connected to the second movable block 20. Due to the cooperation between the first movable block 19 and the first long rod 21, the first long rod 21 can drive the movable plate 22 to rotate along the inside of the first movable block 19. At this time, through the cooperation between the second movable block 20 and the second long rod 23, the second movable block 20 can move left and right along the outer surface of the limiting rod 4 and be sleeved on the outside of the second long rod 23. At the same time, the rotation of the rotating rod 5 can drive the limiting rod 4 to limit the first movable block 19 and the second movable block 20 respectively, thereby fixing the child's legs.

[0031] The two ends of the flexible spring 10 are fixedly connected to the first rectangular block 9 and the second rectangular block 11, respectively. The limiting shaft 12 is movably sleeved with the movable frame 6. Due to the design of the flexible spring 10, when the first rectangular block 9 is in a fixed state, the second rectangular block 11 has good elastic reset performance. At this time, the flexible spring 10 is in a compressed state, so it will apply an elastic force to the second rectangular block 11, thereby driving the limiting shaft 12 into the interior of the movable frame 6 to limit the limiting plate 7. The right side of the movable locking tooth 17 is a right-angled triangle. The movable locking tooth 17 is engaged with the fixed locking tooth 13. Due to the design of the movable locking tooth 17, through the cooperation between the first rectangular block 9 and the round shaft 8, the movable locking tooth 17 can be moved up and down by the mounting plate 14. When the inclined surface of the movable locking tooth 17 presses against the fixed locking tooth 13, the movable locking tooth 17 will move to the left along the outer surface of the round rod 15 and separate from the fixed locking tooth 13, so that medical staff can push the mounting plate 14 downward. At the same time, since the flexible spring 10 is in a compressed state, a pushing force can be applied to the movable locking tooth 17, so that when the movable locking tooth 17 separates from the fixed locking tooth 13, it can drive the first rectangular block 9 to reset, thereby driving the clamping block 18 to separate from the child's arm.

[0032] The rigid spring 16 is fixedly connected to the movable tooth 17 and the mounting plate 14 at both ends. The inner side of the clamping block 18 is covered with silicone. Since the rigid spring 16 is in a compressed state, it will apply an elastic force to the movable tooth 17, which will make the fit between the movable tooth 17 and the fixed tooth 13 tighter. At the same time, since the silicone has good elasticity and softness, it will make the child's arm more comfortable.

[0033] Working principle and usage process:

[0034] First, due to the cooperation between the movable frame 6, the first movable block 19, the second movable block 20, and the limiting rod 4, medical staff can move it left and right along the outer surface of the limiting rod 4. This allows the position of the movable frame 6 to be adjusted according to the position of the child's arm, and the position of the first movable block 19 to be adjusted according to the position of the child's leg. At this time, medical staff can rotate the left rotating rod 5, which allows the limiting rod 4 to move towards or away from each other through the two threads on its outer surface, thus positioning the first movable block 19. Subsequently, the cooperation between the first long rod 21 and the first movable block 19 can drive the movable plate 22 to rotate. Then, the cooperation between the second movable block 20 and the limiting rod 4 can drive the second movable block 20 to engage with the second long rod 23. This allows the second movable block 20 and the movable frame 6 to be positioned by rotating the right rotating rod 5. Therefore, the fixed position can be adjusted according to the child's height.

[0035] Subsequently, through the cooperation between the second rectangular block 11 and the circular shaft 8, medical staff can pull the second rectangular block 11 upward along the outer surface of the flexible spring 10. At the same time, due to the cooperation between the movable frame 6 and the limiting plate 7, the limiting plate 7 can rotate along the top of the movable frame 6. Then, the operator can release the second rectangular block 11. At this time, since the flexible spring 10 is in a compressed state, it will apply an elastic force to the second rectangular block 11. Thus, the limiting plate 7 can be limited by the cooperation between the limiting shaft 12 and the movable frame 6 to prevent the limiting plate 7 from rotating, thereby quickly limiting the child's arm.

[0036] Meanwhile, due to the cooperation between the first rectangular block 9 and the circular shaft 8, the first rectangular block 9 can move up and down along the outer surface of the circular shaft 8. Thus, medical staff can use the mounting plate 14 to drive the movable locking tooth 17 to squeeze the fixed locking tooth 13. When the inclined surface of the movable locking tooth 17 is squeezed against the fixed locking tooth 13, the movable locking tooth 17 will move to the left along the outer surface of the circular rod 15 and separate from the fixed locking tooth 13, so that the mounting plate 14 can be released from its limit. Then, the clamping block 18 can be driven by the first rectangular block 9 to fit more tightly against the child's arm. At this time, since the rigid spring 16 is in a compressed state, it will apply an elastic force to the movable locking tooth 17. Thus, the clamping block 18 can be positioned by the cooperation between the movable locking tooth 17 and the fixed locking tooth 13, so as to prevent the child's arm from moving.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
